I just bought a new i7 rig. 920 (D0), GB EX58-UD3R, Stock cooling, 6GB GSkill 1600 NQ.
I ran Prime95 and managed to get through the tests with a max of 68c on one of the cores.
Is it safe to mildly overclock this rig on stock voltage with these temps?
Sorry it this is pretty straight forward however, this is my first OCíng adventure.
Cheers.

Just to emphasize what OilFieldTrash said --

The stock thermal wattage spec for the I7 under load is supposed to be around 130W. Over-clocking it will increase the thermal wattage. You need to get either a top-end heatpipe cooler (like the $60-something Megahalem), or implement a water-cooling solution.

68C on one core would be normal for the stock cooler I think, given your room-ambient temperature (because it will vary with that). Unless I'm mistaken -- having not yet taken the plunge to I7 yet -- you're within the thermal spec for that core.

But you really need to get better cooling -- both within the case in general (if you haven't already) and for the CPU. Then -- over-clock that sucker!

Oh well. I was trying to see if I could avoid buying an aftermarket cooler after shattering my budget for this rig. I guess it can wait until payday!

You DO NOT need an aftermarket cooler to mildly overclock your 920
I've successfully o/ced mine to 3.6ghz using the stock cooler getting similar temps to yours.

Can you run Linpack/LinX/Intel burn test for 12-24 hours on the stock cooler at those clocks? If not, then it's not a valid overclock.

A stable system isn´t defined by a 24hours test. I know no one (even enthusiatic users) who run heavy CPU demand programs for 24 hours straight. For example, the most CPU demanding aplication I execute is "Calculate Sky Acessibility" in the CryEngine2, and it takes something about 30minutes...

And hey guys, why are my temps THAT HIGH?

Those things are going to be screamers, I settled on these Panaflos to place in a push/pull configuration on my TRUE 120. This will be my 3rd remount to achieve desired temps. I also have 3 of these Yate Loons2 cooling the hard drives and video card and 1 as an exhaust.

Yes, for 24-48hrs at least.
He is asking for a mild overclock and everyone knows that intel stock cooling is good for that. I am shocked to see some members to even suggest getting an aftermarket cooler for this.

I consider 3.6ghz a moderate to high overclock and I find the stock cooler to do its job with it as well.

Stable means it can not be crashed. The only way to crash a stable system would be with buggy software.(The hardware itself is rock solid) If your machine is able to be crashed if you run intense enough software for a long enough time, your machine isn't stable. People who say it is are only fooling themselves.

Hmm if I recall correctly when I was OCing my core i7 to 3.0 I would only reach 72 -74. It was a mild overclock but I knew I would have to remount my TRUE 120 because I used too much Artic Silver 5 so I didn't try to achieve my previou 3.6 overclock. At 3.6 OC 1.35 vcore I was getting temps in the mid 80's. I'm going to remount my cooler for a third time and install 2 new fans in a push/pull configuration and hopefully I can go back to overclocking:cool:

Seems to me your Vcore is just very high. Sounds like an unlucky i7 purchase.

Doing 1.24V at 3.8 GHz 180x21 with temps maxed at 75.

Sounds like your heat sink may not be mounted well..
You did say stock cooler, right ?

One of the push pins may be loose..
